Longitudinal cohort. ⋯ Patients with lumbar degenerative disorders have health state values similar to patients with chronic renal disease, Crohn's disease, or coronary artery disease. Health state values of patients with different indications for surgery differ at baseline and after surgery. Revision cases have worse baseline SF-6D scores and less improvement in scores at 2 years after surgery than primary cases. Further studies are needed to gain a greater understanding of health state utility values in patients with lumbar degenerative disorders.

Multicenter Study
Expression of ezrin, MMP-9, and COX-2 in 50 chordoma specimens: a clinical and immunohistochemical analysis.
Retrospective study. ⋯ En bloc resection with tumor-free margins is seldom feasible, particularly in the sacrum. Intralesional excisions mostly end in early local recurrence; therefore, the demand for further treatment options is frequently posed. The marked trend of the investigated biomarkers of this study may build a starting point for further investigations as molecular targets for future adjuvant therapies in chordomas. Future multicenter studies on larger patients' series are necessary to elucidate these preliminary data and to test new treatment options for patients with chordomas.

Comparative Study
Gender difference in association between low back pain and metabolic syndrome: locomotive syndrome and health outcome in Aizu cohort study (LOHAS).
Cross-sectional survey. OBJECTIVE.: To investigate the relationship between low back pain (LBP) and metabolic syndrome (Mets) in community-based Japanese subjects. SUMMARY OF BACKGROUND DATA.: Relatively few reports have demonstrated a relationship between general pain and Mets, and none have addressed the relationship between LBP and Mets. ⋯ We observed a tendency toward higher prevalence of Mets among those with LBP than among those without it in women, but not in men.

Retrospective, single-institution review of adult deformity patients who underwent iliac screw (IS) removal placed during fusion to the sacrum. ⋯ Of 395 consecutive walking patients who had ISs placed during fusion to the sacrum for adult spinal deformity, 24 (6.1%) underwent elective removal. Patients had a statistically significant improvement in hip/buttock pain after IS removal, and a low prevalence of complications after the procedure was observed.

Case Reports
Implant failure of Bryan cervical disc due to broken polyurethane sheath: a case report.
A case report. ⋯ This case demonstrates the unique incident of broken Bryan disc after 8 years of implantation. Follow-up imaging shortly after the procedure should be mandatory to monitor such potential complication.
